Abstract

This course explains the fundamentals of waveform
design for multiple sensor systems. Although, this
course emphasizes the waveform design for radar
sensors, the design approaches are easily applicable
to other sensors such as sonar, wireless
communications, infrared and UWB. A primary goal of
this course is to present waveform design trade
space and choices a designer should make in
optimizing the waveform parameters for a given
sensor application. The course reviews the necessary
linear system principles for understanding the
waveform design trades. Several waveform design
examples are presented that are suitable for typical
radar applications. Waveform characteristics are
compared for selecting an optimal waveform for a
given application. Waveform modulations covered in
this course include LFM, NLFM, polyphase codes,
Costas codes, Barker codes, shift-register codes,
quadratic residue codes, and chaotic codes. Waveform
sidelobe suppression techniques are also presented.
High Range Resolution (HRR) waveform design concepts
are reviewed for wideband processing.
